c++ - C++11 线程是否为分离线程提供了一种在主线程退出后继续运行的方法？

Question

通常，当 main() 退出时，所有线程都会被杀死。 pthread_exit(3) 说

To allow other threads to continue execution, the main thread should terminate by calling pthread_exit() rather than exit(3).

是否有等效的 C++11 API 调用？像 std::this_thread::exit(0) 这样的东西？

Answer 1

Working Draft, Standard for Programming Language C++ 的第 1121 页从 2012-01-16 开始似乎声明一旦主线程退出，它的分离线程也将被清理(除非我误解它):

void detach();

Requires: joinable() is true.

Effects: The thread represented by *this continues execution without the calling thread blocking. When detach() returns, *this no longer represents the possibly continuing thread of execution. When the thread previously represented by *this ends execution, the implementation shall release any owned resources.

Postcondition: get_id() == id().

Throws: system_error when an exception is required (30.2.2).

Error conditions:

— no_such_process — if the thread is not valid.

— invalid_argument — if the thread is not joinable.
